WFS Standard Jacket Sizing Chart
In order to choose the correct size for your jacket, measure your height, chest and waist circumferences in cm. When taking your measurements, be sure to have your chest protector (if any) and underplastron on, in order to avoid any sizing mistakes. If you do not own any chest protector / underplastorn, then give some allowance in your measurements. For fast-growing children, it may also be advisable to order a bigger size.
